2019 Reprint of 1923 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition software. Sefer, Book of Formation, or Book of Creation is the title of the earliest extant book on Jewish esotericism, although some early commentators treated it as a treatise on mathematical and linguistic theory as opposed to Kabbalah. Yetzirah is more literally translated as "Formation"; the word Briah is used for "Creation". The book is traditionally ascribed to the patriarch Abraham, although others attribute its writing to Rabbi Akiva. Modern scholars have not reached consensus on the question of its origins. According to Rabbi Saadia Gaon, the objective of the book's author was to convey in writing from a Jewish perspective how the things of our universe came into existence. Translated from the Hebrew, with annotations by Knut Stenring. Includes the 32 paths of wisdom, their correspondence with the Hebrew alphabet and the Tarot symbols and with an introduction by Arthur Edward Waite.
